A career with a high starting point and a large development space——network engineer
The starting point of network engineers is very high, and they are in a position of high salary and high status. According to the survey data released by the China IT Industry Association, the current monthly salary of one year of work experience can generally reach 6,000-8,000 yuan, and the annual salary of some senior network engineers is generally as high as 100,000. The development space of network engineers is very large, they can be database engineers, network security engineers, network administrators, etc.; with the accumulation of experience, they can be senior network engineers, project supervisors, project managers, and even start their own businesses!
Network Engineer Prospects
The career life of a network engineer is long, and the salary of a network engineer will continue to increase with your experience. With the accumulation of experience, you can choose a variety of positions.
Network Engineer Employment
Network engineers are highly skilled occupations. The company values technology and experience and will not dismiss them casually. In addition, there is a relatively large gap in the position of network engineers, and there is a great shortage of talents. A statistical data from ChinaHR.com shows that there are more than 600,000 network engineers in short supply every year, and this number is increasing rapidly with the popularization of the Internet in China!
